FemtoLine product group includes a selection of nonlinear and laser crystals for femtosecond applications. For second and third harmonic generation of Ti:Sapphire laser we offer thin BBO crystals. You could also take a look at Femtokit – complete solution for third harmonic generation of Ti:Sapphire. For frequency conversion of Yb:KGW/KYW we offer a choice of LBO and BBO crystals. Yb:KGW and Yb:KYW crystals with broad emission bandwidth are used as lasing material to generate ultrashort high power pulses.
Nonlinear BBO crystals for efficient frequency conversion of femtosecond Yb:KGW or Yb:KYW lasers. The thickness of BBO crystal should be chosen according to your application and fundamental wavelength pulse duration. Apertures up to 25x25 mm on request.
EKSMA OPTICS recommends these LBO crystals for Type 1 SHG at 1030 nm depending on fundamental wavelength pulse duration, assuming it's spectrum limited Gausian pulse.
Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are used as lasing materials to generate ultrashort (~ 100-200 fs) high power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser systems.
BBAR coating, a multilayer dielectric antireflection coating, is designed to minimise dispersion of ultrashort pulses and also features high damage threshold.
Calcite plates for femtosecond-scale time delay compensation between fundamental and harmonic pulses with orthogonal polarizations. Precise time delay value can be adjusted by angular tuning of the GVD compensation plate (AOI range ±10°).
The optical material used for cross-polarized wave (XPW) generation is Barium Fluoride (BaF2) crystal with z ([001]) or holographic ([011]) crystallographic orientation. We offer [011] orientation crystals for XPW generation.
